Evaluation of Biomarkers Involved In Bone Metabolism (Remodeling) In Periimplanter Crevicular Fluid of Implants With Early Marginal Bone Loss: A Retrospective Clinical Study
This study aimed to compare biological mediators known to be important in peri-implant diseases in implants with and without early stage marginal bone loss.
A total of 118 implants in 59 patients were designated as test and control groups.
The radiographic and periodontal data of the included implants, along with peri-implant sulcus fluid samples, were evaluated.

상세 설명
This study included clinical and radiographic records of patients who received implant treatment in the maxilla and/or mandible between 11/2021 and 9/2024.
Patients were divided into test and control groups based on the presence/absence of EMBL after prosthetic loading.
Periodontal clinical measurements were recorded and peri-implant sulcus fluid (PISF) samples were collected.
Sclerostin, calprotectin, type I collagen cross-linked N-telopeptide (NTx), matrix metalloproteinase (MMP)-8, and MMP-9 levels were analyzed using ELISA.
Group comparisons were performed with the statistical analyses.

Radiographic detecting of Peri-implant marginal bone loss
기간: Baseline, 3 months
|
The amount of marginal bone loss was determined by comparing the periapical radiograph taken on the day the implants were placed with the radiograph taken at 3 months.
Measurements of digital radiographic images were performed using computer software.
Then, study groups were determined according to the presence or absence of peri-implant marginal bone loss.

Modified Bleeding İndex
기간: During the same session as the peri-implant fluid collection procedure
|
This assessment was performed based on the bleeding response following gentle probing with a plastic probe in the four regions of each implant (mesial, distal, palatal/lingual, and buccal).
The severity of bleeding observed within approximately 10-30 seconds after probing was scored and recorded.
The scoring system was graded as follows: 0: no bleeding, 1: bleeding at a single point, 2: bleeding at several points or in a linear pattern, 3: heavy bleeding following probing.

Peri-implant pocket depth
기간: During the same session as the peri-implant fluid collection procedure
|
A plastic periodontal probe was used to determine peri-implant pocket depth.
Measurements were taken by using the probe, supported by its own weight, parallel to the long axis of the tooth.
Pocket depth was measured at 6 sites (mesio-buccal, buccal, disto-buccal, mesio-palatal/lingual, palatal/lingual, disto-palatal/lingual) for each implant included in the study and recorded in millimeters (mm).
The pocket depth value for each dental implant was obtained by calculating the average of the 6 measured values.

Gingival İndex
기간: During the same session as the peri-implant fluid collection procedure
|
The mesial, distal, buccal, and lingual/palatal surfaces of each tooth/implant were evaluated separately, and the average of the scores obtained was recorded as the gingival index value for that tooth/implant.
Scoring during the evaluation was performed as follows: 0 = normal gingiva, 1 = mild inflammation (color change, mild edema, no bleeding on probing), 2 = moderate inflammation (redness, edema, bleeding on probing), 3 = severe inflammation (marked redness, edema, ulceration, spontaneous bleeding).
Subsequently, all values were summed and divided by the total number of teeth and implants to record the gingival index score.

Modified Plaque İndex
기간: During the same session as the peri-implant fluid collection procedure
|
The mesial, distal, buccal, and lingual/palatal surfaces around the teeth/implants were examined, and the average of the scores obtained for each surface was recorded as the plaque index for that tooth/implant.
The scoring criteria were as follows: 0 = no plaque, 1 = plaque detectable only with a probe, 2 = soft plaque accumulation visible to the naked eye, 3 = the tooth surface covered with a distinct plaque layer.
Subsequently, all values were summed and divided by the total number of teeth and implants to record the modified plaque index score.

Peri-implant mucosal recession
기간: During the same session as the peri-implant fluid collection procedure
|
The abutment-implant interface was designated as the reference point for determining the extent of peri-implant mucosal recession, and the distance between the reference point and the free gingival margin was measured using a periodontal probe.
Mucosal recession was recorded in four regions (mesio-buccal, mid-buccal, disto-buccal, mid-lingual/palatal) for each implant included in the study.
The recession value for each implant was obtained by calculating the average of the four measured values.
